This should be an easy one as it is a quite old socket LGA 775 motherboard. I want to try whether a LGA 771 Xeon would work in this motherboard, so that's why I request the unlock of the BIOS - as well as seeing if the motherboard has overclocking features hidden. If it was possible, it would be helpful if the microcode for all LGA 771 and LGA 775 cpu was included. As I know how to do it myself, it is okay if it is not.
